The unavoidable conclusion is that the unprecedented meekness of the majority is responsible for the increase in violence. Social stability is the product of an equilibrium between a vigorous majority and violent minorities. Disorder does not come from an increased inner pressure or from the interaction of explosive ingredients. There is no reason to believe that the nature of the violent minorities is now greatly different from what it was in the past. What has changed is the will and ability of the majority to react.
It is hard to tell what causes the pervasive timidity. One thinks of video-induced stupor, intake of tranquilizers, fear of not living to enjoy the many new possessions and toys, the example of our betters in cities and on campuses who high-mindedly surrender to threats of violence and make cowardice fashionable.
